How Exchange Rate Markups Work: The Hidden Cost in Remittances
Understand how financial institutions construct retail exchange rate spreads, why Google rates differ from provider quotes, and how to spot them.
Why sending an international wire through your local retail bank is usually the most expensive and slowest way to move money abroad.
The Traditional Banking Trap
When consumers need to move money across international borders, their default instinct is often to log into their familiar checking account (Chase, Bank of America, Wells Fargo, Citi, Barclays) and set up an international wire transfer.
While banks are trusted institutions for domestic checking and mortgages, traditional international bank wires are frequently the slowest and most expensive method available.
The Three Layers of Traditional Bank Wire Costs
- Outgoing Wire Fee: Commercial retail banks charge an upfront fee between $25 and $45 simply to initiate an international SWIFT wire.
- Intermediary / Correspondent Deductions: Traditional international wires route through the SWIFT network. Along the way, one to three intermediary correspondent banks may deduct handling fees ($15 to $30) directly from the principal before it arrives.
- Large Exchange Rate Spreads: The largest hidden cost. Commercial banks typically quote retail exchange rates with markups between 2.5% and 4.0% above the mid-market rate.
How Specialized Fintechs Eliminate These Costs
Specialized providers (like Wise, Remitly, and Instarem) do not send your money across international borders via SWIFT.
Instead, they maintain local domestic bank accounts in each country:
- You send a domestic ACH or Faster Payment to their local account in the US or UK.
- Their automated system instructs their domestic account in India to send an instant local IMPS/NEFT transfer to your recipient.
- The money never actually crosses a physical border, eliminating SWIFT network fees and intermediary bank deductions entirely.
